    So, my "new" pedal assembly from Brewer's arrived at my house while I'm still on the road, and I have some questions about swapping the assemblies so it'll speed things up when I finally get around to doing it. I do plan on going with a hydraulic throwout bearing, so that bypasses anything I would have asked about the Z-bar stuff.


    Will I need anything extra as far as the pedal assemblies themselves go?
    How long will it typically take?
    Will I need to visit a chiropractor after I'm done?

    I am a bit confused. I (just) went to Brewer' website ( Brewer's Performance - Mopar A833 4-Speed Transmission and Component Specialists ) and found three different repo petal sets. One for '66-67 B-body, one for '68-70 B-body and last for '71-74 B-body/all E-body.

    The C-body uses a different set as well as the A-body and also for pickups/fans have their own set.
    And, FMJ's also have a different set.

    Which petal set of theirs did you get?


    The A-body petal set should be the closest setup to FMJ (in theory) – but not done a side by side comparison of them to know how much, if anything, is the same.
    Here is a petal set from a '79 F (black) and petal set from a '84 Gran Fury (rust colored).

    (Note: F/M body with cast iron brake master cylinder will have a slightly different bolt pattern – but that only matters if you are using manual brakes).

    The metal frame is the same on both petal sets, as well as the stop light switch..
    Everything else is different – and that includes the petals, the pivot shaft (is longer for the second petal) and the left side bracket. The firewall has two extra holes in it. The factory uses a reinforcement bracket (goes in from engine side of firewall), part # 2950680 ( Firewall Clutch Reinforcement Bracket Fits 71-74 B-Body and E-Body Mopar Cuda | eBay ) for that side bracket.

    This is a couple of pictures I collected that shows the master cylinder install (both from an A-body):

    Hopefully this helps,

    Hmmm, who'd of thunk it. Another company that actually acknowledges Aspen and Volare were ever built. That's a damn rare thing, unfortunately.

    That's the set I used on my 82 Dip years ago. Got it out of a parts car and it fit well

    The spring is the hardest thing to find if you don't have one.

    Look at post #2 (the black, or 3-petal setup) and you will find the before mentioned return spring.
    Hopefully, your petal setup came with one . . .

    Yes, the return spring. The good thing about taking a parts car apart, or back when these were even available in junkyards, was you "usually" had all of the parts. Now, when Joey Bag O' Donuts has one for sale, most of the time the smaller important stuff is missing, because it wasn't that important to his third cousin who took it apart. Also, as this stuff gets dinosaur old, you can't just go to the stealership if you lose a part or buy incomplete assemblies.

    Well, I guess I’ll find out if it has it Friday when I get home.

    Without the over center spring, it takes more effort to depress the pedal. With a diaphragm pressure plate, not having the spring isn't such a big deal. If you had a Borg and Beck or 3 lever type plate, without the spring you'd blow out a knee, lol. That one from Brewers in the link says it has no over center spring or pin.

    The spring does nothing until the pedal is pressed a certain amount and the spring goes over center, then it assists the pedal by pulling it down. Kind of like a "power clutch".

    Besides, if you go with a hydraulic clutch set up, the spring is not needed. In fact, if there was one, you'd need to remove it when converting to hydraulic anyways.

    That’s good news at least. Now I just need to find a T56 or a TR6060 that’s not gonna cost me a kidney.

    I've read somewhere that a member had modified a 3 peddle assembly out of a first gen Dakota. Does anyone have insight or thoughts on such an adventure?

    I have heard that, as well.
    So far, I hadn't found a 3-petal 1st gen Dakota to verify.

    I could be mistaken, but I also heard the 2nd gen Dakota has hydraulic clutch that can be converted for our use - but, again, I hadn't found one to verify.

    How difficult could it be? Pedal assemblies are not as complex as some of the other stuff we have to deal with, so if you find something close you should be able to make minor modifications and go with it. The Dakota is probably close enough. There are so few manual transmission vehicles these days, finding anything with pedals is becoming the hardest part of this type of project.
